Hi guys.
i was today watching a movie via the newest samsung MHL cable available, i believe mhl 2.0 11 pin, when my battery went too low. i hadn't yet used the adapter with the power cable attached so i thought it would simply carry on as normal but be charging the phone as well.
unfortunately the phone started disconnecting then connecting every couple of seconds. as soon as disconnected the power cable, it connected again and played fine, albeit with a reducing battery.
as far as i am aware the adapter should be fine with this setup as confirmed by the adapter having a power socket on it.
any idea what is wrong with it?
anyone have an idea on this?
It could possibly be a weak power supply. Did you use the one that came with the phone?

It's possible it's a faulty power adaptor? - never used MHL so can't speculate too much myself tbh
cheers guys.
i have tried 2 power adapters now, one being for my nexus 7 in case it provided extra juice but both had the issue.

Hey guys. I seem to be having a problem with my Android HD2. It seems that the phone recognizes certain chargers as USB. The phone allows the option to enable USB Mass Storage and turns on debugging mode.
Normally, this wouldn't be a problem since the phone still charges fine, except for the fact that it limits the incoming current to 280mA. The main charger for my HD2 is a powermat which puts out 1A but when the phone is dropped onto the mat it recognizes it as USB and limits the charging current to 280mA so it charges rather slowly. All the powermat receiver door is connected by is 2 pins. The little 3 pin interface that is underneath the battery door is where it interfaces at via thw two outer pins one for + and one for -.
I thought I had seen this issue on XDA before but for the life of me I can't find the article. I thought I remembered someone saying that you had to short something with a resistor to stop the phone from thinking the charger is USB. Does anyone know of this problem?
I have the same issue and looking for any answers. Using Android 2.3.2 on HD2.

I've had this issue with apple chargers. I am guessing here but I think it is because the iphone chargers send some sort of authentication data to the phone as a measure against unauthorized chargers. See this link for more info
http://www.ladyada.net/make/mintyboost/icharge.html
makes total sense i have heard of that its sort of a self protection
Yes, the new batch of apple chargers have some of the USB pins connected together to indicate that the device may draw more than 400mA from the charger.
It prevents my eBook from charging completely!
The only real way to fix it would be to butcher a USB cable to only connect the 2 power lines.
there are a few threads that talk about how to make some in car chargers NOT get recognised as a car kit, and that uses the same technique mentioned above, , ,namely shorting some of the pins. I assume the same principle will work here. You just need to find out which pins it is.
Any info on this would be well appreciated.
Don't know if this is already covered somewhere but I can't find it. I'm well gutted about this, Just tried watching a film on HTC ONE with OTG cable and it doesn't work. I get a warning notification saying " unable to charge device, please use supported charger " Gutted. I thought this would of been covered since the one-x supported OTG when it got 4.1 update. Also, don't know if it's related but the MHL (an official HTC 1) isn't working properly either as it did on my one-x. It wil be playing fine for 20/30 seconds and then cuts off for 10 seconds then comes back on. It's does this repeatedly which makes what ever your trying to watch - unwatchable.

It supports OTG
Haven't tried mhl, but otg works fine here.
Tried it with my memory sticks and fiio dac.

Seem to be working now. Must of been the memory card adapter I tried, tried another one and ok now but still getting error notification " unable to charge device, please use the supported charger " Don't know what that's all about. Keyboard and mouse work fine with OTG, never tried them before.

Definitely something wrong with MHL.just tried again with official HTC adapter and flawless on one-x, unstable on the ONE.

Isn't the one purportedly MHL 2.0? Maybe the adapter needs to be different...

I just tried MHL on my One using the official HTC M490 adapter (NOT the M500 which I think won't work). I have no problems at all with MHL. It is stable. I don't know what difference MHL 2.0 makes, but I did notice that the phone seems to be capable of outputting something different to MHL out, vs what is on the phone screen.
For example, and I have no idea why, I seem to have a free copy of Thor on the phone under the HTC Watch application (freebie?). I found that when I choose Thor as the film, the phone screen is showing a synopsis, while the TV is showing a still frame from the movie. However, when actually playing the film, both are showing the same thing. Nevertheless it is a good indication that dual screen gaming applications may be possible for example.
Also tried the OTG using a Samsung usb adapter. No problems functionally but I can confirm the misleading error message about not being able to charge the phone. No problems accessing the USB storage though and Gallery automatically will find pictures on an externally mounted SD card.
HTC M500 adapter has 12 pins and was the adapter for HTC tablets (Flyer and Jetstream). The majority of connectors use 5 pins, except Samsung (SIII and Note 2) that uses 11 pin, which allows for MHL and USB OTG simultaneously.
Regarding MHL 2.0, it has the ability to pass 1080p video at 60Hz (up from 30Hz of MHL 1st generation) and charge up to twice as fast. Samsung SIV has it, but I haven't find anything official that shows HTC One also has it, or for the need of a different adapter.
All the MHL adaptors i've seen (mine included- Cablesson) have a micro USB slot so you plug in your charger* to that, then the device to your phone, and it charges as it outputs.
Are you all doing that, or trying to output with no charger attached.

I have no problems but to confirm the adapter won't even start-up if you don't connect the charger...it is totally ignored. I am assuming the original poster either has a bad USB/MHL port on the phone, or the adapter is slightly out of tolerance with its connections hence working on some phones and not others.
I've bought an adapter on ebay for my One X. Besides ths usb charging port having issues, it messed my One X usb port - it only worked with the adapter pluged in. I had to reset One X. So, mhl adapters can be really a mess.

First day with phone today so briefly trying lots of things, I had pre-bought cheap ebay MHL adaptor and tried it with a few youtube videos seems to work OK (confirm you must have a charger micro-usb MHL).
It did give about 20 secs of white snow interference at start almost as though it was tuning in channel but steady after that.
More investigations to follow I think.

How did you get on after more tests?
can you link me to the one you purchased if all worked fine please
if anyone else has a 100% working MHL to HDMI can you post which one and where to purchase.

Sucks that I don't have mine yet. I have two different MHL adapters I could try.
I just experienced the original "HTC AC M490" MHL-Adpater with my HTC One (Stock ROM).
It was working straightaway, but the device display as well as the TV screen where a little bit slow and choppy.
Is it possible to change some settings (like resolution or frame rate) to improve the performance?
THX
Edit: Is it MHL 2.0 ? (Regarding to this thread it seems to be only MHL 1.0)?

No, it isn't.
The S4 will be the first MHL 2.0 spec device.
Is there any way to set the output resolution manually to 720p?

With a custom kernel you can do this. Flar2 did this for the one XL, I see he's starting to migrate over here.

Yes obviously plugged the charger in aswell with the MHL. The picture is perfect. It just play's for 20/30 seconds then cuts out for a couple and just keeps doing that. Even though the OTG works I still get the error triangle in the notification bar, which I don't on my ONE-X, but I can put up with that.

I installed it in my dash and removing it is a pita it was working perfectly fine but for some reason it wasnt showings charge or turning off or on with the car it just stays on i tried restart nothing happens i tried unplugging usb from powergen and plugging back in no result
Also if i go to usb rom under fixed installation i am able to check box and uncheck also did nothing
I am using nexus 7, timurs usb rom, otg cable, original charging cable and powergen usb charger
Please help thanks
Anyone???
I'm also using Timur's kernel with USB ROM for my car installation. I know that it can be very picky on the order the USB plugs are added (data and power). It may seem simple but remove the the OTG cable from the tablet and remove both the data and power legs from the OTG as well. The follow the order listed by Timur on his website:
To activate charging, you must first connect your external power supply to your OTG Y-adapter - then plug the OTG adapter into your Nexus 7 - and then connect any slave devices.

Hopefully that should get you back up and working. I completely understand how frustrating it is to have everything plugged in and see that tablet isn't charging, especially when its difficult to get to the Nexus itself.
does anyone have a easy charging solution these car chargers dont work
and a good otg y cable
You could try using a power inverter which will give you a standard US plug from the cigarette lighter. From here, you could plug in a regular outlet adapter. I found this to work pretty well with my own set up and managed to get one pretty cheap at Walmart. As for a good OTG y cable, your best bet is probably to go on Amazon and find one with a lot of good reviews. They can vary in quality and some of the cheap ones I've gotten from China have flaked out after a short time and little use.

Not seeing usb power
I had the same issue. I was using a 90 degree adapter into an OTG cable and my n7 wouldn't go into fixed install mode. Turns out my adapter cable was stopping the n7 from recognizing power. I removed the 90 degree adapter and plugged straight to otg and it worked as advertised. The issue was found during my bench testing on a 12v powersupply. I still have to find a 90 degree otg cable that will work.
So... try a different cable or if you have an adapter between the otg y cable, that may be the issue.
I'm on 4.4.2 stock rooted, and using a MHL/HDMI cable I bought from eBay (http://www.ebay.com.sg/itm/271413587689).
When I plug it in (including the charging USB cable), my Note 3 detects that a HDMI cable has been connected. However, nothing appears on the TV (I tried different HDMI ports). I have also tried restarting my phone as per the instructions on the eBay page.
What does happen is that the display on my Note 3 lags and stutters when the cable is connected. But no matter what I do, I can't get the screen to be mirrored on my TV.

Yes you can. It's also helpful if you want to use a wireless usb controller since it needs the power boost. Here's what I use: https://www.ebay.com/itm/Left-Angle...361414?hash=item48830dbec6:g:rQsAAOSwMmBV5RRC

My pleasure! I have a bluetooth keyboard case. I mostly use it for flash drives and it charges while in use. I also have those devices plugged into my firesticks at all times so I can transfer video files easier and never had a problem

Thanks for the confirmation. I had been using this cable (https://www.amazon.com/Tendak-Micro...07828&sr=1-2-spons&keywords=otg+y+cable&psc=1) for my Nexus 7 I had installed in my dash, and for some reason it just doesn't work with my HD 8. Even with the USB DAC not connected, the cable registers power, charges for about 30 seconds, then says it's not connected to power anymore. don't have this issue with the Nexus, or with any of my other power cables, but that's the only OTG angle cable I have.
I'll try the one you use, but I'll have to use a Micro USB angled extension to make it fit in the dash. Unless someone else knows of an OTG y cable with an angled plug that actually works for the HD 8?
Update: I've bought two additional otg cables from Amazon, and one will work for the usb device, but doesn't charge the tablet, the other charges the tablet, but won't work for the usb device. After testing both of these several times, they both started to have the same behavior as my other one, it shows charging for a few seconds, then stops, but continues to power the usb device. If I connect a normal power cable it will stay in "fully charged" mode forever and Automate reports power is connected. I'm starting to get really frustrated. I'm pretty sure it is actually charging, because when I left it connected like that for an hour, it never moved from 85%, but then as soon as I plugged in a normal charging cable it started "charging" at about 6% per minute, and said 100% within 3 minutes. Not even a QC 3.0 can do that. I'm so confused.
